In This Article
16:8 intermittent fasting is the ultimate beginner protocol: you fast for 16 hours each day and consume your meals within an 8-hour window (typically 12:00 PM to 8:00 PM). By eliminating late-night snacking and skipping breakfast, your body spends 8 to 10 hours daily in active fat burning without requiring complicated diet rules or calorie deprivation.
⚡ 16:8 Beginner Checklist
- Choose Your Window: 12:00 PM to 8:00 PM is the most popular and easiest to maintain.
- Fasting Rules: Water, black coffee, and plain unsweetened tea only during the 16 hours (coffee fasting rules).
- Meal Structure: 2 balanced meals + 1 healthy snack during your 8-hour window.
- Hydration Target: Drink 2.5–3.5 liters of water daily (calculate your water target).
What a Typical 16:8 Day Looks Like (12 PM – 8 PM)
- 8:00 AM: Wake up, drink 500ml water with a pinch of pink salt, enjoy a black coffee.
- 12:00 PM (Meal 1 – Break Fast): Grilled chicken salad with avocado, quinoa, olive oil, and feta.
- 3:30 PM (Snack): Greek yogurt with berries and walnuts.
- 7:30 PM (Meal 2 – Dinner): Baked salmon, sweet potato, and roasted broccoli.
- 8:00 PM: Fasting timer begins in FastingTracker.
